Answer:

Yes the car was speeding

Step-by-step explanation:

               s = √(30fd) where

  •    s is the speed of the car in mph
  •    f is the coefficient of friction for the road
  •    d is the length in feet of the skid marks

Substitute d = 41.5 and f = 0.8 into the equation:

    s = √(30 x 0.8 x 41.5)

⇒  s = √(996)

⇒  s = 31.55946768...

Therefore, for these data, the speed of the car was 31.56 mph (to the nearest hundredth)

The speed limit was 30 mph, therefore the car was speeding as 31.56 > 30

Shane and abha earned a team budget that required their team to collect no less than 2000 cans for recycling. Abha collected 178
TiliK225 [7]

Answer:

s ≥ 911

Step-by-step explanation:

Let

s = number of cans Shane could collect

Abha collected 178 more cans than Shane did.

Abha = s + 178

Shane and Abha earned a team badge that required their team to collect no less than 2000 cans for recycling

Number of cans collected by Shane + number of cans collected by Abha ≥ 2000

s + 178 + s ≥ 2000

2s + 178 ≥ 2000

2s ≥ 2000 - 178

2s ≥ 1,822

Divide both sides by 2

s ≥ 1,822 / 2

s ≥ 911

Since we know the slope is 3 we have part of the equation already (y=3x+b). Now we need to find the y-intercept. To do that we plug in the point that was given to us in the question and solve for b.

0=3(-5)+b
0=-15+b
15=b

Now that we have the y intercept we can put the equation together.

Answer: y=3x+15

Hope this helps :)

 A garden is 5 yards 12 inches wide and 6 yards long. Write the ratio of the width to the length as a fraction in simplest form.
musickatia [10]
8/9 because there are 36 inches in a yard and you need to convert all the yards to inches and turn it into a fraction. The original fraction is 192/216 but it simplifies to 8/9.
